<p>学习资料：https://www.bilibili.com/video/av50680998/?p=46</p>
<p>动画能够提高用户的体验，帮助用户更好的理解页面中的功能</p>
<h2 id="原理">原理</h2>
<p>在进入/离开的过渡中，会有 6 个 class 切换：</p>
<p><img src="https://gitee.com/leafsing/pic/raw/master/img/20200709014341.png" alt=""></p>
<ul>
<li>*-active 可以理解为时间段（2个），其它为时间点（4个）</li>
<li>v-enter/v-leave-to 样式相同，v-enter-to/v-leave 样式相同</li>
</ul>
<h2 id="入门-自定义样式实现动画">入门-自定义样式实现动画</h2>
<p>步骤一：使用<code>transition</code>标签封装动画元素或组件</p>
<pre><code class="language-html">    &lt;div id=&quot;app&quot;&gt;
        &lt;!--需求：点击按钮，让 h3 显示或隐藏--&gt;
        &lt;input type=&quot;button&quot; value=&quot;toggle&quot; @click=&quot;flag=!flag&quot;/&gt;
        &lt;transition&gt;
            &lt;h3 v-if=&quot;flag&quot;&gt;这是一个H3&lt;/h3&gt;
        &lt;/transition&gt;
    &lt;/div&gt;
</code></pre>
<p>步骤二：自定义两组样式，来控制 transition 内部元素实现动画</p>
<pre><code class="language-html">    &lt;style type=&quot;text/css&quot;&gt;
        /*进入至离开，两个时间点*/
        .v-enter,
        .v-leave-to{
            opacity: 0;
            transform: translateX(150px);
        }
        /*两个时间段*/
        .v-enter-active,
        .v-leave-active{
            transition: all 1s;
        }
    &lt;/style&gt;
</code></pre>
<p>对于这些在过渡中切换的类名来说，如果你使用一个没有名字的 <!-- raw HTML omitted -->，则 v- 是这些类名的默认前缀。</p>
<p>如果你使用了 <!-- raw HTML omitted -->，那么 v-enter 会替换为 my-transition-enter。这样可以不同组的变化 ——20190927</p>

<p>总结：</p>
<ul>
<li>钩子函数的第一个参数 el ，是指要执行动画的那个 DOM 元素，是一个原生的 JS 对象</li>
<li>beforeEnter(el) 表示动画进入之前，动画尚未开始，用于设置元素开始动画之前的样式</li>
<li>enter(el,done) 最后要记得调用 done() 函数</li>
<li>afterEnter(el)</li>
</ul>
<blockquote>
<p>当只用 JavaScript 过渡的时候，在 enter 和 leave 中必须使用 done 进行回调。否则，它们将被同步调用，过渡会立即完成。</p>
</blockquote>
<p>其实 done 指的就是 afterEnter 这个函数，是引用 afterEnter 。——vue教程-黑马-205集完整版 p50</p>

<p>问：为什么每次点击按钮，小球都从开始位置执行动画？</p>
<p>答：因为在 afterEnter 函数中，将 flag 置为 false ，跳过下半场动画动。画从头开始执行了，也就是从 beforeEnter 开始重新执行。</p>
